Abstract

Modular Multilevel Converter (MMC) is becoming a strong alternative converter for Voltage Source Converter (VSC) due to its control and flexibility. Considering the importance of the losses estimation in the design process, an analytical method is proposed to calculate the power losses in each switching device of a sub module of Modular Multilevel Converter (MMC). Average and root mean square of the sub module current is used to calculate the conversion losses (conduction and switching). The method is applied on a full bridge sub module topology. Then considering a case, with certain parameters a MATLAB program is developed to analyze the results for the proposed method.
